Oven capable of decreasing temperature forcedly for lithium ion battery production

The utility model discloses an oven capable of decreasing temperature forcedly for lithium ion battery production. The oven comprises an oven inner cavity, a heating layer, an insulating layer and an oven outer wall from inside to outside, wherein a cooling layer is arranged between the oven insulating layer and the heating layer; a cooling medium can be circulatingly guided in the cooling layer; the cooling medium is deionized water; and the deionized water is obtained by converting tap water via a deionized water production system. According to the oven capable of decreasing temperature forcedly for lithium ion battery production, the temperature decreasing time after baking materials can be greatly shortened, thereby improving the production efficiency; and as the cooling medium adopted by the cooling layer is deionized water which is produced by the deionized water production system, hot water after circulating in the oven cooling water layer can be used in the case of negative electrode glue mixing, wate
